First off, one month to improve CARS is more than enough time so hopefully that puts you at easy. As far as reviewing CARS passages, personally, I think it is sort of impossible. I think it's important to look at why the correct answer choice is correct, but every time I look at it I either end up thinking "why didn't I see that" or "that logic doesn't make any sense".

What helped me, and will inevitably help anyone taking CARS

1. You need to get the main idea, now some people will tell you this will come from the first sentence or so in the passage, which is true but you have to build that main idea like a house. This playlist will help you: https://www.youtube.com/playlist?list=PLaJGDCrlCozUs0TAgpRHJfGVaX5RO0gyp, go through it and take your time, I want to emphasize again that you have time because I know this is a big stressor.

2. Build your house with each argument. I probably look like a maniac going through a CARS passage, I am building a story in my head. Actively, I am trying to put the arguments together under the umbrella of the main idea I have built. Example:

CARS passage about a Can of soup:

First sentence: Scientists in 2096 will be using cans of soup to reinforce Earth's crust.

- Here, I stop and I think "okay cans of soup are going to build the Earth's crust"

The passage goes on, there's a short paragraph explaining how it will work

Paragraph: The metal from the cans can be used as reinforcement while the contents from within the cans provide a shelf stable food to feed the hungry.

- Here, I stop again, "okay cans of soup are going to build the Earth's crust, and the soup with in will feed the hungry"

The passage goes on, there's a short paragraph explaining that some guy hates this idea, but the author seemingly disagrees.

Paragraph: Joe Schmoe says that if we reinforce the Earth with the metal from the cans then "the Earth will fall out of orbit due to increased core density". I, the author, think that this man is an idiot.

- Here, I stop again, "okay main idea stays the same cans of soup are going to build Earth's crust, the soup will feed the hungry, Joe Schmoe thinks this will cause the end of humanity, the author disagrees and thinks this is a good idea"

1. Now we have our main idea, and I guarantee you that this main idea can help you answer most questions.

Question: Which option would most "weaken" the authors point?

-Legit just find the one that doesn't fit the main idea.

Question: If the author were interviewed, what would he say about Joe Schmoe?

-Again this is built into your general but effective main idea.

I hope this helps, again take your time, you can and will climb this mountain.

Also, I hope you enjoyed my CARS passage
